Question

VWhich sets of ordered pairs show equivalent ratios? Use the grid to help you. Check all that apply. (1, 2), (2, 3), (4, 7) (2, 2), (4, 4), (6, 6) (3, 1), (4, 1), (5, 1) (4, 1), (8, 2), (12, 3) (2, 1), (4, 3), (5, 4)

Answer 1

B-2, 2), (4, 4), (6, 6)

D-(4, 1), (8, 2), (12, 3)

Explanation:

Took quiz and got it right

Answer 2

(2, 2), (4, 4), (6, 6)

(4, 1), (8, 2) (12, 3)

Explanation:

We want to to choose from the following, the ordered pairs that show equivalent ratio:

A. (1, 2), (2, 3), (4, 7)

B. (2, 2), (4, 4), (6, 6)

C. (3, 1), (4, 1), (5, 1)

D. (4, 1), (8, 2), (12, 3)

E. (2, 1), (4, 3), (5, 4)

The ordered pairs that are equivalent have the same ratio when in simplest

form.

For instance (2, 2), (4, 4), (6, 6) have the simplest form 1:1, when the coordinates are simplified.

(4, 1), (8, 2) (12, 3)

are equivalent because

8:2=4:1

12:3=4:1

The rest of the ordered pairs are not equivalent because their coordinates are not in the same ratio.
